autocmd! followed by <bar>

[Lifepillar]

It seems impossible to have autocmd! followed by another command, i.e.:

autocmd! some_group | <whatever I put here is ignored>

According to `:help autocmd`, autocmd may be followed by another command
when the '|' appears before {cmd}. This does not seem to be the case for
autocmd!. Is that intentional?

Thanks,
Life.

Help says "this works":
:augroup mine | au! BufRead | augroup END

but it doesn't (augroup "mine" still active afterwards), thus it can't be
intentional and you found a bug.

Also not working:
:augroup mine | au! BufRead *| augroup END
" `*|' is taken as autocmd-{pat}, `augroup END' becomes {cmd}

:augroup mine | au! BufRead * | augroup END
" uses `| augroup END' for {cmd}

Weird that it went unnoticed for so long, probably because most people
instead use
:au! mine BufRead

I think Vim should make anything after `:au' part of the command.
`:au' is already listed under `:h :bar' without further notice.

I second this, there already are at least five variants of handling
command separator (bar), comment start (double quote) and escaping
characters. Let’s not make rules surrounding bar/dquote/backslash even
more weird by adding an exception.
